Description

Die Erfindung betrifft eine Verkehrssignalleuchte, ins­ besondere Kraftfahrzeugrückleuchte mit einem Leuchtfeld für die Anzeige des Bremsvorganges und einem Leuchtfeld für die Anzeige des beabsichtigten Richtungswechsels.The invention relates to a traffic signal light, ins special motor vehicle rear light with a light field for the display of the braking process and a light field for the display of the intended change of direction.

Verkehrssignalleuchten sind in vielfältigen Ausführungs­ formen bekannt. Insbesondere sind auch Zusatzleuchten bekannt, die für die Anbringung im Rückfenster eines PKW bestimmt sind. Diese Zusatzleuchten sollen dem nachfol­ genden Verkehr etwaige Bremsvorgänge des vorausfahrenden Fahrzeugs noch deutlicher anzeigen, als die fest am Kraftfahrzeug installierten Kraftfahrzeugrückleuchten, und zwar dadurch, daß sie auch durch die Fenster eines vorausfahrenden PKW sichtbar sind.Traffic signal lights are in a variety of designs known shapes. In particular there are additional lights known for mounting in the rear window of a car are determined. These additional lights are said to traffic, any braking of the vehicle in front Show the vehicle even more clearly than the fixed on Motor vehicle installed rear lights, by the fact that they also through the windows of a cars driving in front are visible.

Den Verkehrssignalleuchten der eingangs genannten Art ist gemeinsam, daß sie geteilte Leuchtfelder aufweisen, die in verschiedenen Leuchtfarben aufleuchten, bei­ spielsweise in rot zur Anzeige des Bremsvorganges oder in gelb zur Anzeige des beabsichtigten Richtungswech­ sels. Die oben diskutierten Zusatzleuchten haben sich in ihrer Funktion zwar bewährt. Die Verwendung dieser Zu­ satzleuchten ist in jüngster Zeit jedoch zurückgegangen, weil aufgrund der großen Leuchtstärke dieser Zusatz­ leuchten die nachfolgenden Fahrer geblendet wurden. Die relativ hohe Leuchtstärke ist erforderlich, weil die Leuchtflächen verhältnismäßig klein sind.The traffic signal lights of the type mentioned has in common that they have divided light fields, that light up in different fluorescent colors, at for example in red to indicate the braking process or in yellow to indicate the intended change of direction sels. The additional lights discussed above have become in proven their function. The use of this To  set lights has recently declined, because of the high luminosity of this additive the following drivers light up. The relatively high luminosity is required because of the Luminous areas are relatively small.

Es ist Aufgabe der Erfindung, die Verkehrssignalleuchte der eingangs genannten Art dahingehend weiterzubilden, daß die die jeweilige Funktion anzeigenden Leuchtflächen besonders groß sind, ohne daß sie eine Blendwirkung ha­ ben. Darüberhinaus sollte die Möglichkeit bestehen, im Bedarfsfall mittels der Leuchtflächen mehr Information an den Verkehr geben zu können.It is an object of the invention, the traffic signal light of the type mentioned at the outset, that the illuminated areas indicating the respective function are particularly large without having a glare ben. In addition, there should be the possibility of If necessary, more information by means of the illuminated areas to be able to give to traffic.

Zur Lösung dieser Aufgabe schlägt die Erfindung ausge­ hend von der Verkehrssignalleuchte der eingangs genann­ ten Art ein neuartiges Leuchtfeld vor. Und zwar hat die Verkehrssignalleuchte gemäß der Erfindung ein einziges, großflächiges Leuchtfeld, auf dem mit engem Abstand zueinander eine große Zahl von Mehrfarb-Leuchtdioden angeordnet ist, die mindestens zwei Leuchtfarben haben und mittels einer Steuerschaltung in jeweils ausgewähl­ ten Gruppen in einer oder mehreren Leuchtfarben an­ steuerbar sind.To achieve this object, the invention proposes Starting from the traffic signal light called a new type of illuminated field. And that has Traffic signal light according to the invention a single, large-area illuminated field on which at a close distance to each other a large number of multi-color LEDs is arranged, which have at least two fluorescent colors and selected in each case by means of a control circuit groups in one or more fluorescent colors are controllable.

Bei Verwendung der Verkehrssignalleuchte gemäß der Er­ findung als Kraftfahrzeugrückleuchte steht zur Anzeige der jeweiligen Funktion, z. B. Bremsen oder beabsichtig­ ter Richtungswechsel, im Normalfall die gesamte große Leuchtfläche zur Verfügung, indem beispielsweise für die Anzeige des Bremsvorganges alle auf dem großen Leucht­ feld angeordneten Mehrfarb-Leuchtdioden in der Farbe rot angesteuert werden. Es ergibt sich mithin ein großflä­ chiges, gut sichtbares Bremssignal für den nachfolgenden Verkehr, welches aufgrund der geringeren Leuchtintensi­ tät der einzelnen Leuchtdioden nicht blendet. Ebenso können für die Anzeige eines beabsichtigten Fahrtrich­ tungswechsels alle Mehrfarb-Leuchtdioden des Leuchtfel­ des in der Farbe gelb angesteuert werden, so daß sich ein großes, weithin sichtbares und dennoch nicht blen­ dendes Fahrtrichtungssignal ergibt. Dieses Fahrtrich­ tungssignal kann natürlich - gesteuert durch einen ent­ sprechenden Blinkgeber - in herkömmlicher Art und Weise blinken. Wird das Kraftfahrzeug während der Fahrtrich­ tungsanzeige zusätzlich gebremst, werden die Mehrfarb- Leuchtdioden auf einer Hälfte des großflächigen Leucht­ feldes in der Farbe rot angesteuert, während die ver­ bleibenden Mehrfarb-Leuchtdioden weiter in der Farbe gelb blinken. Ein weiterer Vorteil besteht darin, daß bei Ausfall einzelner Leuchtdioden - anders als bei Rück­ leuchten mit Glühlampen - die Funktion noch voll ge­ währleistet ist.When using the traffic signal light according to the Er invention as a motor vehicle rear light is on display the respective function, e.g. B. braking or intentional ter change of direction, usually the entire big one Illuminated area available, for example for the Display of the braking process all on the large light multi-color LEDs arranged in the field in the color red can be controlled. This results in a large area Good, clearly visible brake signal for the following Traffic, which due to the lower light intensity  the individual LEDs do not dazzle. As well can be used to display an intended driving lane change all multi-color LEDs of the light panel of the yellow are controlled so that a large, widely visible, and yet not pale end direction signal. This driving line ting signal can of course - controlled by an ent talking flasher - in a conventional way flash. Will the motor vehicle during the driving line display is braked additionally, the multicolor Light-emitting diodes on half of the large-area light field in the color red, while the ver permanent multicolor LEDs continue in color flashing yellow. Another advantage is that in the event of failure of individual light-emitting diodes - unlike with back light up with light bulbs - the function is still fully functional is guaranteed.

Bei Verwendung der Verkehrssignalleuchte gemäß der Erfindung als Ampel oder Verkehrsleitsystem können eben­ falls auf einem sehr großen Feld weithin sichbare und dennoch nicht blendende Informationssignale gegeben wer­ den, deren Inhalt beliebig gestaltbar ist.When using the traffic signal light according to Invention as a traffic light or traffic control system can just if widely visible in a very large field and nevertheless not giving dazzling information signals to anyone those whose content can be designed as desired.

Zur Erfüllung der vorstehend geschilderten Funktionen ist die Schaltung bei der Verkehrssignalleuchte gemäß der Erfindung so ausgebildet, daß einerseits alle Mehr­ farb-Dioden des Leuchtfeldes entweder in der einen oder in der anderen Farbe ansteuerbar sind und daß anderer­ seits zur gleichen Zeit ein Teil der Mehrfarb-Leuchtdio­ den des Leuchtfeldes in einer Farbe und der verbleibende Teil der Mehrfarb-Leuchtdioden des Leuchtfeldes in der anderen Farbe ansteuerbar sind. To perform the functions described above is the circuit in the traffic signal light according to the invention designed so that on the one hand all the more color diodes of the light field either in one or are controllable in the other color and that other at the same time part of the multicolor LED that of the light field in one color and the remaining one Part of the multi-color light-emitting diodes of the light field in the other color can be controlled.  

Eine besonders bevorzugte Ausführungsform der Erfindung sieht vor, daß die Steuerschaltung einen programmier­ baren Mikroprozessor zur Erzeugung von beliebig bestimm­ baren Leuchtsymbolen auf dem Leuchtfeld versehen ist. Hierdurch ist es möglich, auf dem Leuchtfeld bestimmte Symbole, gegebenenfalls auch Buchstaben, erscheinen zu lassen, welche dem nachfolgenden Verkehr bestimmte Gefahrensituationen anzeigen oder sonstige Informationen geben. So kann beispielsweise auf dem großen Leuchtfeld, z. B. in der Farbe rot das Wort HELP erscheinen, wenn Hilfe benötigt wird. Ebenso kann bei Verkehrsstau das Wort STAU erscheinen. Bei der Verwendung der Kraftfahr­ zeugrückleuchte gemäß der Erfindung im Rückfenster von Polizeifahrzeugen können beispielsweise zu kontrollie­ renden Fahrzeugen Anweisungen gegeben werden, wie BITTE FOLGEN, RECHTE FAHRSPUR FREIHALTEN, VORSICHT UNFALL, KEINE BRENNENDEN ZIGARETTEN AUS DEM FENSTER WERFEN, usw. Gegebenenfalls kann die gelb blinkende Fahrtrichtungsan­ zeige auch in Form eines gelb blinkenden Pfeiles er­ scheinen, welche zusätzlich erkennen läßt, in welcher Richtung der vorausfahrende Fahrer die Fahrtrichtung zu ändern beabsichtigt.A particularly preferred embodiment of the invention provides that the control circuit a programm baren microprocessor to generate any visible light symbols is provided on the light field. This makes it possible to determine certain on the light field Symbols, possibly also letters, appear leave which determined the following traffic Show dangerous situations or other information give. For example, on the large illuminated field, e.g. B. the word HELP will appear in red if Help is needed. Likewise, in the event of traffic jams Word JAM appear. When using the motor vehicle Rear taillight according to the invention in the rear window of For example, police vehicles can be used to control Instructions are given to vehicles such as PLEASE FOLLOW, KEEP RIGHT ROAD, CAUTION ACCIDENT, DO NOT THROW THE BURNING CIGARETTE, etc. If necessary, the yellow blinking direction of travel also show it in the form of a blinking yellow arrow seem, which additionally shows in which Direction of the driver driving ahead the direction of travel intends to change.

Zweckmäßig ist bei der zuletzt genannten Ausführungsform die von dem Mikroprozessor gesteuerte Steuerschaltung mit einer Eingabetastatur verbunden, welche es ermög­ licht, die verschiedenen Symbole auszuwählen oder gege­ benenfalls neue, anzuzeigende Wörter zu bilden.It is useful in the last-mentioned embodiment the control circuit controlled by the microprocessor connected to an input keyboard, which made it possible light to select the various symbols or if necessary, to form new words to be displayed.
